Characteristics of the bottom scrapers


Scrapers are mainly used in sewage treatment plants and water treatment plants, where they collect waste accumulated in sedimentation tanks. There are several main types of these devices on the market, differing in design and purpose. One of them is the bottom scraper. Here you can read what exactly they are characterized by.How does the bottom scraper work?
A bottom scraper is a device designed to thicken and remove bottom sediments. It consists of an appropriate number of scrapers with a hydrodynamic profile, which are usually made of high-quality steel (for example, Swedish). The scrapers are welded together, resulting in one movable grate, which is used to move the bottom sediment to the sump. The scraper produces cyclic reciprocating movements over the entire surface of the bottom of the sump, which create a zone of turbulence. As a result, the sludge is constantly compacted. The work performed should not interfere with the deposition process.Construction of moving parts
Modern models of bottom scrapers move with the help of energy-saving hydraulic cylinders, so they do not require the use of additional chains, ropes or trolleys. Fewer moving parts guarantee long and trouble-free operation of the equipment. The bottom scraper should consist of standard elements, so that it can be easily adapted to almost all settling tanks, even existing ones. If its operation is equally effective with both pushing and pulling drives, the drive can be located on both sides of the sump. In rectangular settling tanks with an area of up to 100 m2, the hydraulic drive can be replaced by an electric motor specially designed for this purpose.What else is worth knowing?
The optimal hydrodynamic solution for various types of deposits is a wedge-shaped scraper with a concave pressure surface. Depending on the type of sludge, the speed of the scraper can be adjusted. At the bottom of the sump, the bottom scraper moves along three or five sliding rods made of high-molecular polyethylene. Such slats reduce the abrasion of the scraper sections. It is expected that their service life will be about 10 years. They are attached to the bottom of the sump with dowels. Their installation and replacement are simple. On the other hand, the installation of the entire sump takes several days. Management and control are carried out through the electrical cabinet.
